![]() ![]() ![]() Of course, a plastic at 250 degrees Celsius is not cooled to room temperature as quickly as a plastic at 180 degrees Celsius … The temperature of the printing bed and the ambient air is one such factor, but the temperature of the plastic during printing is also important. How quickly this happens depends on various factors. ![]() But as soon as the plastic leaves the nozzle, it cools down. The filaments join and fuse together while the plastic is still warm and flexible. Your printed piece is built up from these threads. The liquid plastic is repeatedly laid next to and on top of each other in individual threads via fine nozzles. plastic so that the material becomes liquid. Your 3D printer heats a material made of polymers, i.e. To do this, change the plate adhesion type to Skirt.īut one thing at a time: Why exactly would you need a Raft for better adhesion to the printing bed? Small components, filament properties and temperature If you want to save printing time and material, you can deactivate the Raft. This is the case with most Cura profiles. If you are working with Cura, the Raft may even be enabled by default. Depending on the shape and size of your printed piece, or depending on the material you use, you may have trouble keeping the 3D printer bed clean.How do you remove the substructure again? That is sometimes not so easy!.There are alternatives, and they can actually make more sense. However, the Raft is never the only option. If your printer works with a perforated printing bed, a Raft is also beneficial.If the printed part has a small contact area, fix it in place using a Raft.If a warped printing bed shows height differences, these can be compensated for using a Raft.If more support is needed on the printing bed, a Raft is an option.There are four reasons for adding a Raft to a printed part: What is a Raft for and How & When to Use it? 5 Conclusion: Raft → A Great Tool for Adhesion!.3.4 Check the printing plate before printing.3.3 Allow sufficient time for the first layer.3.2 Adjust the distance between Noozle and build plate.3.1 Check the alignment / leveling of the printing bed.1.5 Small components and cold printing bed.1.4 PLA and ABS adhere better on a warm printing bed.1.3 Example ABS: 230 ☌ and up to 2% Shrinking.1.2 Why does cooled down filament not adhere?.1.1 Small components, filament properties and temperature.1 What is a Raft for and How & When to Use it?. ![]()
